Imagine the F1, a rocket engine that spends almost 3 tons of fuel per second. It has to fire for 160 seconds. Try to imagine a tank containing that much fuel. The tank has to withstand the vibrations of being lifted by a rocket engine. Now imagine 5 of those engines. You have just the first phase of the Saturn V rocket that took three men to the moon.
